BIOMOLECULES AND ENZYMES

Detailed explanation-1: -All living organisms are composed largely of proteins–which are coded for by genes. Proteins are large, complex molecules made up of long chains of subunits called amino acids. Twenty different kinds of amino acids are usually found in proteins.

Detailed explanation-2: -All living organisms are made up of one or more cells, which are considered the fundamental units of life. Even unicellular organisms are complex! Inside each cell, atoms make up molecules, which make up cell organelles and structures. In multicellular organisms, similar cells form tissues.

Detailed explanation-3: -Proteins are large, complex molecules that play many critical roles in the body. They do most of the work in cells and are required for the structure, function, and regulation of the body’s tissues and organs.

Detailed explanation-4: -Proteins are the major ‘working molecules’ within every organism. Among their many jobs, proteins catalyse reactions, transport oxygen and defend organisms from infection. They’re also crucial building blocks of organisms.
